OFFICE auasiz mivrcs roa name commas ALLY 10 It, accordingly, is an object my invention to provide an apparatus of simple construction which may be easily handled or permanently positioned in a place where its function may be most desirable in practice, and which is prefer- 15 ably operated by an electrically driven motor or some other suitable means, having aian attached thereto and through its rapid rotation creatin an air current which is permitted to pass into a concentrator wherein a plurality of electrically 20 heated elements are positioned, thus creating a blast 01 hot air at the tapered end or mouthpiece of said concentrator and to provide a shell surrounding the concentrator in spaced relation thereto together with a construction whereby air 25 exhausted from a container may be directed into said shell,

The above, and further objects and advantages of my invention as will hereinafter more fully appear, I attain by the construction shown and 30 described in this specification and illustrated on the drawings forming a part of my application.

Reference is had to the accompanying drawings in which the reference characters denote similar parts.

Describing my invention more in detail, said invention comprises of a housing A which is adapted to receive a motor 4 at one end, having a cover,

associated therewith as at G and the opposite end 15' of said housing is adapted to receive a concen- R trating drum ii, preferably smaller in diameter and terminating with a conically shaped mouthpiece- It, as shown.

Carried on the housing A is a shell 2 having a tapered outer end portion l2 and which shell is 7 piece i6 which encloses the mouth piece ill with its reduced end margin spaced from said mouth piece thereby forming an opening around the mouth piece communicating with the chamber l4. The end 01 the tapered conical end piece i6 is spaced inwardly from the end of the mouth piece.

Internally within said drum 8, I. have positioned a plurality of elements i8 whichmay be of any desired configuration and are mounted upon a hollow shaft 20 held in place by means of a collar 22 locked by a split washer 24, permanently located in the groove 26, having spacing collars 28 positioned therebetween and locked in place by means of a nut 30, as shown in Fig. 3.

Said shaft 20 is secured to a center section 32 comprising a hub 34 wherethrough said shaft 2|! protrudes and is held in place by means of a split locking collar 35; said center section 32 is provided with a plurality of air circulating holes 38- having an apron 40 equipped with a plurality 01' slots 42, extending inwardly into the chamber 44 wherein the air pressures are created by means of a Ian 46, driven by said-motor- 4, having the inlet air holes 48 positioned asshown.

The concentrating drum 8 is also equipped with 50 a flared out base section ll which insulates saidv drum I from the chamber 44 and the cooling shell ,2, which is also equipped with holes 52 which holes may serve either as warm air outlets or cold airinlets.

The drum 8 is also equipped with a heat retaining means 53, such as asbestos or other material mostdesirable in practise, which is for the purpose of preventing the radiation of heat from such shell 8 into the chamber l4.

In the Fig. 8, I have shown an extension shell 54, preferably of tapered construction which comprises a shell 56, the base flange 58 which is used for attaching it to the end piece I 6, having the nozzle 60 terminating with a protector 62, comprising strip 64 attached as shown.

Internally within said shell 54, I have positioned a centralizing ring 66 which may be of any desired length or width and which is for the purpose of holding said extension shell 54 in place, and by reason thereof extending the hot air currents beyond the mouthpiece i 0, thus creating a concentrated hot air pressure at the opening 68 and a very effective vacuum, which draws the cool air through the holes 52, through the space 10, around the drum 8 and within said cooling shellv l2.

-In the event it may be desirable to extend the mouthpiece NJ for the purpose of heating or to direct the hot air in places not easily accessible, I have provided said extension 54, and the nozzle 60, with a binder 52 which is for the purpose of holding a flexible hose M, or other tubing material in place, and which may be substantially secured to said nozzle 68 by means of a clam 16 as shown in Fig. 10.

The housing A is also provided with a handle 18 so that the apparatus may be carried easily from place to place and in order to place said apparatus in a convenient position, I have provided it with legs 80 which may be of any desired shape and may be, if preferred, used for attaching said apparatus to a floor, walls or the like. The apparatus is also provided with a switch 82 which makes the contact between the motor 4 and the heating elements i8 which are con- I nected in series by means of lead wire 84.

, In operation, the fan 46, turning at high speed, draws the air into the chamber 44 through the inlet openings 48, forcing it against the base section and between the slots 42 of the apron 40, passing through the openings 38 within the drum 8 circulating around said elements 18 and emerging at the mouthpiece Ill and when the end piece It is inserted in an opening of a vessel or a barrel, as the case may be, the draft or blast of hot air passing through said mouthpiece It! will effect displacement of air within the vessel or barrel and cause such displaced air to flow to discharge from the interior thereof around the mouth piece I0 and into the end piece l6 through the passage l4 and through the holes 52. In event the extension shown in Fig. 8 is emplayed the hot air discharging from the mouth piece it will effect reversal of flow of air through the passage l4 as before stated and in this instance the displaced air from the vessel or barrel will. be permitted to flow to atmosphere around the tapered shell 54.

In Fig. 12, the tapered mouth piece I 8 is shown as formed with a tubular extension 85 and carried on said extension in spaced relation to the outer end thereof is a cone fitted with fins 86 which cone is tapered to be inserted in the bung hole of a barrel and with the fins contacting the margin of the hole whereby displaced air may be caused to flow between the fins 86 and into a cylindrical projection 81 on the mouth piece l6 of. the shell 2 and into the passage I 4 and out the openings 52. Also in the construction shown in Fig. 12 the drive shaft 89 of the fan or blower 46 is connected to the drive shaft of the motor through a conventional clutch 90. The shell 2 may be lined with an insulating material indi- 15 cated at 9| between which and the drum 8 a spacing member 92 is interposed.

While I have thus described my invention with great particularity, it will be clear that the same may be modified throughout a wide range. accordingly, do not propose to be limited to the exact details of construction as shown and described in this specification and reserve the rights in practice to make any and all modifications which may come within the scope of the appended claims.
